1 Cyp2a6 is a principal enzyme involved in hydroxylation of 1,7-dimethylxanthine, a main caffeine metabolite, in humans. Caffeine cytochrome P450 family 2 subfamily A member 6 Homo sapiens
2 In a caffeine test previously performed with healthy Japanese volunteers, we found that the CYP1A2 index defined as urinary {5-acetylamino-6-amine-3-methyluracil (AAMU)+1-methylxanthine (1X)+1-methyluric acid (1 U)}/1,7-dimethyluric acid (17 U) was affected by the whole deleted allele of CYP2A6 (CYP2A6*4). Caffeine cytochrome P450 family 2 subfamily A member 6 Homo sapiens
